因为之前jmeter压测，满足不了高并发压测，为了解决，探索使用locust进行压测，一下为locust的使用文档，使用并总结：

打开命令提示符（或Linux终端），输入 `locust --help` 。

> locust --help
    Usage: locust [options] [LocustClass [LocustClass2 ... ]]
    
    Options:
      -h, --help            show this help message and exit
      -H HOST, --host=HOST  Host to load test in the following format:
                            http://10.21.32.33
      --web-host=WEB_HOST   Host to bind the web interface to. Defaults to '' (all
                            interfaces)
      -P PORT, --port=PORT, --web-port=PORT
                            Port on which to run web host
      -f LOCUSTFILE, --locustfile=LOCUSTFILE
                            Python module file to import, e.g. '../other.py'.
                            Default: locustfile
      --csv=CSVFILEBASE, --csv-base-name=CSVFILEBASE
                            Store current request stats to files in CSV format.
      --master              Set locust to run in distributed mode with this
                            process as master
      --slave               Set locust to run in distributed mode with this
                            process as slave
      --master-host=MASTER_HOST
                            Host or IP address of locust master for distributed
                            load testing. Only used when running with --slave.
                            Defaults to 127.0.0.1.
      --master-port=MASTER_PORT
                            The port to connect to that is used by the locust
                            master for distributed load testing. Only used when
                            running with --slave. Defaults to 5557. Note that
                            slaves will also connect to the master node on this
                            port + 1.
      --master-bind-host=MASTER_BIND_HOST
                            Interfaces (hostname, ip) that locust master should
                            bind to. Only used when running with --master.
                            Defaults to * (all available interfaces).
      --master-bind-port=MASTER_BIND_PORT
                            Port that locust master should bind to. Only used when
                            running with --master. Defaults to 5557. Note that
                            Locust will also use this port + 1, so by default the
                            master node will bind to 5557 and 5558.
      --expect-slaves=EXPECT_SLAVES
                            How many slaves master should expect to connect before
                            starting the test (only when --no-web used).
      --no-web              Disable the web interface, and instead start running
                            the test immediately. Requires -c and -r to be
                            specified.
      -c NUM_CLIENTS, --clients=NUM_CLIENTS
                            Number of concurrent Locust users. Only used together
                            with --no-web
      -r HATCH_RATE, --hatch-rate=HATCH_RATE
                            The rate per second in which clients are spawned. Only
                            used together with --no-web
      -t RUN_TIME, --run-time=RUN_TIME
                            Stop after the specified amount of time, e.g. (300s,
                            20m, 3h, 1h30m, etc.). Only used together with --no-
                            web
      -L LOGLEVEL, --loglevel=LOGLEVEL
                            Choose between DEBUG/INFO/WARNING/ERROR/CRITICAL.
                            Default is INFO.
      --logfile=LOGFILE     Path to log file. If not set, log will go to
                            stdout/stderr
      --print-stats         Print stats in the console
      --only-summary        Only print the summary stats
      --no-reset-stats      Do not reset statistics once hatching has been
                            completed
      -l, --list            Show list of possible locust classes and exit
      --show-task-ratio     print table of the locust classes' task execution
                            ratio
      --show-task-ratio-json
                            print json data of the locust classes' task execution
                            ratio
      -V, --version         show program's version number and exit
